SPECIFICATION forming part/0f Letters Patent No. 598,6OQ, dated February8, 1898. I Application filed August 16, 1897. Serial No. 648,481. (llomodel.)

T0 aZZ whom it may concern:

Be it known that I, GEORGE H. HAMALIAN, a citizen of the United States,residing in Paterson, county of Passaic, and State of New Jersey, haveinvented certain new and useful Improvements in Slat Rolling and LookingDevices; and I do hereby declare the following to be a full, clear, andexact description of the invention, such aswill enable oth-' ers skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

The object of my present invention is to provide a shutter with meansfor rolling the slats to any desired position and locking the same whenin closed position, of simple, strong, and durable construction, quickand reliable in operation, and easily handled.

Theinvention consists in the improved slat rolling and lockingmeohanismand in the combination and arrangements of the various parts thereof,substantially as will. be hereinafter more fully described, and finallyenibodied in the clauses of the claim.

Referring to the accompanying drawings, in which like letters ofreference indicate corresponding parts in each of the several views,Figure 1 is a perspective View of a window and its shutter provided withmy improve ments; Fig. 2, an enlarged front elevation of a portion ofthe shutter, more clearly illustrating my improved slat rolling andlocking mechanism, and for which purpose a portion of the frame has beenbroken away; Fig. 3, a sectional view on the lines a a: of Fig. 2, theslats being shown in full lines; Fig. 4, a view similar to Fig. 3, theslats being shown in reversed position and in full lines; and Fig. 5, anenlarged detail sectional view of a portion of one of the slats and thetrunnion arranged thereon. H

In said drawings, a and 5 represent the bottom and side rail,respectively, and c c c the slats of the shutter, which latter areprovided at opposite ends with trunnions 0, having their bearings in theside rails of the shutter,

all as of usual construction.

The side rail 1) consists of two sections 72 and 12 secured together inany desired manner and provided with vertically-arranged elongated slots12 and b, respectively, forming a channel for the operating rod or barcl. Said rod or bar is provided on its inner face and at certainintervals with a series of horizontal pins d, engaging the screw-eye 0secured in the trunnions c and projecting at right angles therefrom. Thetrunnions c are protected by metal caps or covers 0 for the purpose offurnishing additional strength to said trunnions. Said trunnions c arearranged in cylindrical-shaped holes or sockets if, as clearly shown inFig. 2 of the drawings.

The lower portion of the rod or bar cl is bent outward and forward atsubstantially right angles, as at (1 and projects through an elongatedslot arranged in the sectionb of the side rail 1) and through aconforming slot 6, arranged in a plate 6, secured to said rail in anydesired manner and carrying the bar operating and locking mechanism.

To the free end of the projecting portion 01 of the rodor bar cl ispivotally secured, by means of ascrew e one end of a hook-shaped link f,the other end of which is pivotally secured, as at f, to a diskfrevolubly mounted on a pin f projecting from the plate e and at rightangles thereto. The sleeve of the disk f is squared or polygonal-shaped,as at f and is engaged by a key f for the purpose of convenientlyoperating said disk.

A fiat spring 9 is secured with one end, as at g, to the plate 0 andbears with its other end on the top surface of the disk f for thepurpose of furnishing friction and thus retain said disk in any desiredposition. A screw-boltg provided with an adj listing-nut, penetrates thesaid spring 9 and engages the plate 6 and furnishes means for adjustingsaid spring with relation to the disk f A pin (Z is arranged at aconvenient place within the channel formed in the rail 1) and is adaptedto be engaged by one of the projecting pins d to thus limit the downwardmovement of the bar or rod 61 and the revolving movement of the slats c,as will be manifest.

It must be remarked that the pivot f" for the link f is beyond thevertical center line of the disk f when said disk is in normalposition-that is to say, has passed the dead-cen ter of rotation of thesaid diskwhereby the rod 01 is prevented from being shifted (by simplyoperating the slats) without operating said disk by means of the key aswill be manifest.

When the shutter is to be opened, the key f is rotated until the slatshave obtained the desired position. The spring g, being in frictionalcontact with the disk f retains said disk and thus the slats in saidposition.

It will be manifest that the slat rolling and locking mechanism can bearranged on either side of the shutter or that the same mechanism can beconnected with any ordinary shutter-that is to say, the bar (1 takingthe place of the ordinary slat-connecting bar-in which case the lockingmechanism is secured to the central portion of the lower rail a.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is-

1. In a shutter the combination with the frame and the slats pivotallyarranged therein, of a sliding rod loosely connected with said slats andprovided at its lower end with an outwardly-projecting portion bent atright angles to said rod, a disk revolubly mounted on said frame, a pinor pivot arranged on said disk, a hooked-shaped link pivotally connectedat one end to the projecting portion of the rod and at its other end tothe said pin or pivot on the disk, and a pivot for said disk, said pivotlying between the pivoted connections at the ends of the link, when saiddisk has been rotated to raise said rod to close the slats, all saidparts, substantially as and for the purposes described.

2. In a shutter the combination with the frame and the slats pivotallyarranged therein, of a sliding rod loosely connected with said slats andprovided at its lower end with an outwardly-projecting portion bent atright angles to said rod, a disk revolubly mounted on said frame, a pinor pivot arranged on said disk, a hooked-shaped link pivotally connectedat one end to the projecting portion of the rod and at its other end tothe said pin or pivot on the disk, a pivot for said disk, said pivotlying between the pivoted connections at the ends of the link, when saiddisk has been rotated to raise said rod to close the slats, and a fiatspring carried by the frame and in frictional contact with the topsurface of the disk, substantially as and for the purposes described.

3. In a shutter the combination with the frame and the slats pivotallyarranged therein, of a sliding rod loosely connected with said slats andprovided with an outwardly-projecting portion bent at right angles tosaid rod, a disk revolubly mounted on said frame, a pin or pivotarranged on said disk, a hooked-shaped link pivotally connected at oneend to the proj ecting portion of said rod and at its other end to thesaid pin or pivot on the disk, a pivot for said disk-said pivot lyingbetween the pivoted connections at the ends of the link, when said diskhas been rotated to raise said rod to close the slats, a flat springcarried by the frame and in frictional contact with said disk, and ascrew-bolt, provided with an adj usting-nut penetrating said flat springand engaging the frame for regulating the tension of said spring,substantially as described.

4. The combination With the frame and the slats of a shutter, one of theside rails of the frame being provided with a vertical central channel,of a rod slidingly arranged in said channel and loosely connected withsaid slats and having its lower portion bent outward at right angles tosaid rod, a plate on said side rail and penetrated by a verticalelongated slot, a disk revolubly mounted on said plate, a pin or pivotarranged on said disk, a hooked-shaped link pivotally connected at oneend to the projecting portion of the sliding rod and at its other end tothe said pin or pivot on the disk, and a pivot for the disk andprojecting from the plate, said pivot lying between the pivotedconnections at the ends of the link, when said disk has been rotated toraise said rod to close the slats, substantially as described.

frame being provided with a vertical centralchannel, of a rod slidinglyarranged in said channel and loosely connected with said slats andhaving its lower portion bent outward at right angles to said rod, aplate mounted on said side rail and penetrated by a vertical elongatedslot, a disk revolubly mounted on said plate, a pin or pivot arranged onsaid disk, a hooked-shaped link pivotally connected at one end to theprojecting portion of the rod and at its other end to the said pin orpivot on the disk, a pivot for the disk and projecting from the plate,said pivot lying between the pivoted connections at the ends of thelink, when said disk has been rotated to raise said rod to close theslats, and a fiat spring carried by said plate and in frictional contactwith the top surface of the disk, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this7th day of August, 1897.

GEORGE H. HAMALIAN.
